SUMMARY
The dipole moment in Griffiths' "An Introduction to Electrodynamics" is defined by the equation p = ∫ r' ρ(r') dτ'. The integration is performed over the volume that encloses the nonzero charge density ρ(r'). It is established that there is no necessity to integrate over regions of space where the charge density is zero, focusing only on areas with nonzero values. This clarification ensures a more efficient calculation of the dipole moment.
